RE: Using external REST api in CRM

Hi Pankaj,

You can create a JavaScript function which gets executed when OnSave event of the form triggers.

The function may look similar to this.

function UserAction() { var xhttp = new XMLHttpRequest(); xhttp.open("POST", "Your Rest URL Here", false); xhttp.setRequestHeader("Content-type", "application/json"); xhttp.send(); var response = JSON.parse(xhttp.responseText); }

You can find many examples, if you google.

Once you receive the response, if validated you can let CRM save the record, otherwise you can prevent the save action and display a warning.

saveEvent.preventDefault();

Hope this helps.

Cheers,

Nadeeja

RE: Using external REST api in CRM

Hi Pankaj,

Is your Dynamics 365 is on premise or online.?

Why did you need custom REST API because for address validation any way you are using third party webservice. You can even use plugin

If you still need REST API, Please follow below step

Step:1 If it is online then hosting your custom webservice it must be public

Step:2 In onsave event check if the state and zipcode is get dirty then call your public REST api server using ajax call.

If your CRM is onprimesis

Step:1 Host your site in the CRM server.

Step:2 In onsave event check if the state and zipcode is get dirty then call your REST api server using ajax call.

function onSave(context) {

var saveEvent = context.getEventArgs();

if (Xrm.Page.getAttribute("address1_postalcode").getValue() == null) {

// *** Note: I am using an alert for testing a notification maybe better!

alert("Put in a zip/postalcode!");

saveEvent.preventDefault();

}

else

{

UserAction();

}

}

function UserAction() {

alert("DayTuesday");

// var PCode = Xrm.Page.getAttribute("address1_postalcode").getValue();

// var xhttp = new XMLHttpRequest();

// xhttp.open("POST", "localhost/.../ValidatePostalCode", false);

// xhttp.setRequestHeader("Content-type", "application/json");

//xhttp.setRequestHeader("Accept", "application/json");

//xhttp.setRequestHeader("Content-Type", "application/json; charset=utf-8");

// xhttp.setRequestHeader("Access-Control-Allow-Origin", "https://demotransportcrm.crm8.dynamics.com");

// xhttp.send();

// var response = JSON.parse(xhttp.responseText);

var req = new XMLHttpRequest();

req.open("POST", "localhost/.../GetNoteTypes;, true);

req.setRequestHeader("Accept", "application/json");

req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

req.onreadystatechange = function ()

{

alert("onreadystatechange");

if (this.readyState == 4 /* complete */)

{

alert("readyState");

var response = JSON.parse(req.responseText);

alert(response);

alert("response1");

//req.onreadystatechange = null;

Hi Pankaj,

You need to have "http://" in front of localhost. Try that.

RE: Using external REST api in CRM

Hi Pankaj,

As mentioned by Nadeeja, it is possible to call directly using the javascript but to reuse the same functionality across several and better usability, instead of calling directly in the javascript.

I would recommend using Javascript to Call the CRM Actions for validating the result onSave Event. Please check this link ,how to call CRM Actions using javascript.

In CRM Actions, using C# you can use the following code to call the REST API:

string URL = "REST API URL";

WebRequest request = WebRequest.Create(URL);

request.Method = "GET"; // GET (or) POST

request.ContentType = @"application/json; charset=utf-8";

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

string jsonResponse = string.Empty;

using (StreamReader sr = new StreamReader(response.GetResponseStream()))

{

jsonResponse = sr.ReadToEnd();

}

Hi Pankaj,

If any of the suggested answers help you resolve this problem, please mark them as verified. This is help another person in the future.

To answer your second question;

Microsoft AppSource is similar to Apple Store, where Microsoft makes you go through a strict app validation process. If you not planning to sell your App, there's no need to Publish to AppSource. SImply use solutions to package up and deploy to other systems.

More information can be found in below links.
